#materiyolo phase one

Added API 21 style changes (mostly involving Toolbar).

Praise Duarte!
That's what I'm going to do in the next update now that I know that ActionBarActivity extends FragmentActivity. Not knowing that is the reason I couldn't get it working on older OSes. I already switched to AppCompat theme and I'm making everything extend ActionBarActivity. With my new updates, it's mostly working properly on KitKat.

I have a separate issue that you might be able to help with, too: the new date picker (from Material theme) doesn't do anything when you choose a date. Since it's so new (Google hasn't updated the developer docs for DatePicker as of last night [they updated the design page for DatePicker, though]), I couldn't find anything about why it might not be working online. Did you have to do anything to get the Holo date picker working?
